Description

The method that one kind removes benzo [α] pyrene in fat-soluble natural extract
The application is that the Application No. 201510801297.6 submitted on November 19th, 2015 is entitled " go by one kind The divisional application of China's application of the method for benzo [α] pyrene in grease removal soluble natural extract ".
Technical field
The invention belongs to natural plant extracts technical field, and in particular to one kind removes benzene in fat-soluble natural extract And the method for [α] pyrene.
Background technology
Benzo [α] pyrene is a kind of multiring aromatic hydrocarbon substance with strong carcinogenesis, and chemical property is very steady at normal temperatures It is fixed, it is primarily present in flue gas, smoke from cigarette, the vehicle exhausts caused by burning such as coal tar, all kinds of carbon blacks and coal, oil, with And in the trade effluent such as coking, oil refining, pitch, plastics, also easily produced in the food of high-temperature cooking.Due to the quantity of automobile Increasingly increase, trade effluent, the discharge capacity of waste gas also remain high always, so benzo [α] pyrene in empty gas and water and soil is dirty Dye amount gradually increases, and the natural plants survived by empty gas and water and soil are also unavoidably by the pollution of benzo [α] pyrene.
Capsanthin, lutein and lycopene etc. be all from natural plants extraction obtain have health active it is new Functional natural colorants, it is very popular with the pure-natural biological activity that it is stronger.With the natural extract market demand Amount increasingly increases, security requirement more and more higher of the people to product.Research finds that some produced both at home and abroad are fat-soluble natural Containing trace or micro benzo [α] pyrene in extract, certain risk be present, therefore under the severe situation of food security, It is necessary the minimizing technology of benzo [α] pyrene in exploitation natural extract.
At present, the minimizing technology about benzo [α] pyrene is steamed using charcoal absorption, ultraviolet lighting degraded or high temperature mostly The methods of evaporating removes benzo [α] pyrene in edible oil, is dropped using means such as lactobacillus absorption, strong oxidizer oxidation, burnings individually Benzo [α] pyrene pollution in low environment, and there is not been reported for the minimizing technology of benzo [α] pyrene in natural extract.Naturally Extract is easily tightly held by activated carbon in itself, and very sensitive to illumination, high mild oxidizing agent, is easily oxidized and is faded, be rotten, So directly using the method for above-mentioned removal benzo [α] pyrene, loss of effective components is serious.Therefore, for the spy of natural extract Property, the minimizing technology for specially developing benzo [α] pyrene suitable for natural extract is extremely important.
The content of the invention
The shortcomings that in order to overcome prior art, the invention provides one kind to remove benzo [α] in fat-soluble natural extract The method of pyrene.This method is easy to operate, and loss of effective components is few, it is easy to accomplish industrialization, can effectively remove and fat-soluble naturally carry Take benzo [α] pyrene in thing.
In order to solve the above technical problems, the technical solution used in the present invention is removed in fat-soluble natural extract to be a kind of The method of benzo [α] pyrene, comprises the following steps:
(1)Appropriate solvent is added into natural extract crude product and obtains mixed material;
(2)Mixed material is heated, stirred, cool down, be layered after separate levels, obtain sediment and filtrate;
(3)The sediment is washed with a small amount of solvent, obtains cleaning product and cleaning solution;
(4)Product after washing, low temperature desolvation obtain finished product;Step(2)The filtrate and step(3)The cleaning solution is straight Connect and recycled as solvent.
Step of the present invention(1)In natural extract crude product be fat-soluble natural extract.
Step of the present invention(1)In natural extract crude product be lycopene oleoresin, lutein extract saponification Any one in thing or capsanthin semi-finished product.
Step of the present invention(1)In solvent for ethyl acetate, n-hexane, hexamethylene, No. 6 solvent naphthas, methanol, second Any one or a few in alcohol, acetone.
Step of the present invention(1)The mass volume ratio of middle natural extract crude product and solvent is 1:2.5~5, wherein Natural extract crude product mass unit is kg, and solvent volume unit is L.
Step of the present invention(2)Middle heating-up temperature is 35~65 DEG C.
Step of the present invention(2)Middle cooling means is cooling water cooling or natural cooling, is cooled to room temperature.
Step of the present invention(2)In make the method for feed separation to centrifuge or being separated by filtration;Filter method is plate Frame filters or vacuum filtration;Filter cloth aperture is 300~1000 mesh.
Step of the present invention(3)Middle solvent for use is any one in ethyl acetate, acetone, n-hexane or hexamethylene It is or several;Solid-liquid ratio is 2:1~4:1.
The present invention mentality of designing be:Natural extract crude product matrix is complicated, sticky, more readily soluble in the solvent of heating Solve and scattered, be advantageous to disperse to discharge by benzo [α] pyrene and active ingredient of parcel.
All solvable in ethyl acetate, methanol, ethanol, acetone, n-hexane, hexamethylene, the micro benzo of benzo [α] pyrene [α] pyrene will not also separate out after system cooling;And fat-soluble natural extract dissolves in above hot solvent, but at different temperatures Dissolubility difference it is larger, system cooling after largely can separate out or be layered.Therefore, separated after cooling, you can by benzo [α] pyrene and Other stroma contaminants remove in the lump, then with the further cleaning product of a small amount of good solvent, you can obtain being practically free of benzo [α] pyrene Natural extract, and be dissolved in a small amount of active ingredient in filtrate and cleaning solution and reclaimed in the lump with solvent, put into new one In the production of wheel, loss is reduced, it is cost-effective.
It is using beneficial effect caused by above-mentioned technical proposal:The present invention utilizes benzo [α] pyrene and natural extract The dissolving sex differernce of active ingredient is handled, and product treatment effect is good, high income;Natural extract crude product is purified and benzene It is time saving and energy saving and [α] pyrene removes a step and completed;Processing product solvent for use can reclaim, and recycle, cost-effective, reduce Blowdown and waste.Whole flow process automaticity is high, easy, quickly, can a step obtain benzo [α] pyrene content and be less than 10 μ g/kg Natural extract product, easily realize industrialized production.
